Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction block to which fragments such as automobile tires are attached.

[0002]

BACKGROUND ART Conventionally, rubber materials such as old tires, which have been difficult to dispose of, have been attached to the surface of blocks of pavements and revetments as surface layer pieces, so that reverberant noise, generated noise, abrasion, surface icing, and icing can occur. Many effects were obtained, such as reduction of the impact force and the impact at the time of collision. In the manufacturing method for this purpose, rubber was subdivided and granulated, and a granular rubber plate re-solidified with a resin was manufactured. By this method, it was possible to eliminate the difference between the tire shape and the degree of wear and to make an industrial product of a certain standard.

However, there are drawbacks in that special equipment is required for fragmentation and re-solidification, and the processing is expensive. Further, the rubber obtained by re-solidifying the granular rubber has much lower durability than the original rubber material, and has a drawback that its application in severe environments such as roads and outer walls is limited.

For other materials such as wood, glass and stone, the procedure for subdividing and re-solidifying them into surface layer pieces is the same, and there are similar drawbacks in terms of cost and durability. That is,
Both disadvantages arise because of the fact that the blocks are made to a defined thickness when the material supplied in random thickness is used for the surface layer pieces.

In the past, many attempts have been made to bond rubber pieces to the surface of a concrete block that has been hardened with a high-strength adhesive, but the rubber pieces were peeled off in a short period of time. One of the reasons for this is that the shape of the bonding surface between the rubber piece and the concrete, which is the hardened material, is a simple flat surface, so that the shear load applied to the rubber is not dispersed over a wide surface of the hardened material and is concentrated locally. In addition to the direct acting force on this local area, temperature stress due to changes in daytime temperature and the like repeatedly acted on it, so that peeling inevitably occurred, extending from the local area to the whole area. Because of this phenomenon, the method of bonding by adhesion after the cured body has been cured has a drawback that the long-term strength of bonding is weak.

[0006]

Problems to be solved by the conventional means for solving the above-mentioned drawbacks are that the cost for molding the surface layer piece is high, the strength of the surface layer piece is low, the surface layer piece and the cured product. The weakness in long-term bond strength is 3 points.

[0007]

According to the present invention, as a means for solving the above three points at the same time, a block having a surface layer piece formed as described in claim 1 is used. The main feature of this means is that a time-hardening hardening material such as e-concrete in claim 1 is directly cast on the adhesive portion to form a tight interface, and f the hardening material is added in an appropriate amount. And a cured body is formed so that the entire block is cast into a uniform size.

This feature is that, for example, fresh concrete as a hardened material is directly cast on a viscous material such as a bituminous material to be molded. This will be described with reference to FIG. 1. By this method, the surface layer piece 1, the adhesive portion 2, and the cured body 3 are brought into close contact with each other in terms of a microscopically complicated shape. In addition, by making the surface of the cured product that has been set to be constant, even if the thickness of each rubber piece and the shape of the adhesive surface are different, the product thickness can be easily controlled and blocks of specified standards can be manufactured. It According to this method, the steps of subdivision and granulation are omitted, so that the molding cost is reduced, and since the solid rubber piece is used as it is, the strength of the surface layer piece is high. Also surface layer
1. The adhesive portion 2 and the cured body 3 are in close contact with each other with respect to each other in terms of microscopically complicated shapes. For this reason, the shear stress due to the load applied to the rubber is dispersed to a large number of microscopic protrusions of the hardened body 3 to prevent local stress concentration and increase the strength. In addition, even if strain is repeatedly concentrated in a local area at a bonded portion made of a material such as bitumen, the deformation corresponding thereto prevents the occurrence of peeling, and even if peeling occurs, the strength is restored by contact for a certain period of time. Therefore, the durability of strength is further increased. That is, the block according to the configuration of claim 1 simultaneously solves three problems.

The tackiness or delayed adhesiveness such as bitumen in the above means is to achieve the purpose of exerting an adhesive force after curing with a cured product. For this purpose, the same result can be obtained by using a material or a mechanism that adheres after the curing of the cured product with a delay, such as by delayed heating of the adhesive part or delayed permeation of the adhesive liquid into the adhesive part. Further, it may be replaced with asphalt mixture or other material having a delayed adhesive property. This method is also applied to the case where various materials such as wood chips, plastic pieces, waste tiles and smooth natural stone are used for the surface layer pieces. Despite having desirable properties on the surface of the building, materials that have not been used in the past due to difficulty in adhering to concrete, weak adhesion to hardening materials, and variations in dimensions when supplied. There are many. That is, this block is also a means that enables the use of materials that were difficult to make into a durable product of a certain standard. Further, depending on the application, if various concretes in which the material for adhering to the surface layer piece is used as a binder are used as the hardened body 3, the binder forms the adhesive portion 2 at the same time as the casting, so the step of forming the adhesive portion can be omitted. . Further, since the partial peeling that occurs after the start of use is restored at a high temperature, the durability against peeling is greatly improved.

As described in claim 2, a joint body 34 is provided in at least a part of the joint space 4 between the surface layer piece 1 and the adjacent surface layer piece 1 and is cured by embedding, adhering or protruding. Combine with 3 to integrate. In this case, the movement of each surface layer piece 1 due to the load received is restrained by the underlying hardened body, the peeling resistance increases, and the durability of the bond is significantly improved.

As described in claim 3, the groove or holding arm 7 is formed on the back side of the surface layer piece 1 by processing unevenness, and since the hardened body 3 is also followed, the bonding strength is further increased. In particular, when the holding arm 7 made of rubber or the like locally protruding by baking or adhesion is processed, the holding action of the hardening body 3 of the holding arm 7 restrains the surface layer piece 1 and the hardening body 3 from peeling off. The bond strength of the is improved. When the holding arm 7 is held in the hardened body 3 by undercut, the bonding strength is further improved.

When a plurality of independent blocks are connected as a unit by the mesh body 5 as described in claim 4, the intervals and directions of the array blocks on the site are remarkably improved in accuracy, so that the occurrence of weak points is prevented. Further, since the peripheral blocks cooperatively resist the deviation due to the vehicle load through the mesh body 5, the deviation resistance force is significantly improved. In addition, in a unit in which a large number of blocks are combined, a large number can be handled collectively by a transportation means such as a crane or a unicing, so that there is an advantage that the construction efficiency is significantly improved.

In the block as claimed in claim 5, as shown in FIG. 2, the transverse cutting line 11 parallel to the wheel axis is used.
And the edge line 12 of the side orthogonal to this are substantially orthogonal to each other.
By arranging and arranging in this way, it is possible to prevent the curved shapes peculiar to the back surface of the surface layer from being aligned in one direction or from being aligned on the same surface. Therefore, a unique three-dimensional undulation can be formed on the bonded portion. Since this undulation strongly resists displacement in two directions, it is possible to prevent displacement and peeling of the surface layer piece for a long period of time. In addition, the tread pattern
Anti-slip in two directions to prevent slip accidents.

As described in claim 6, in the block which is laminated and integrated in a sandwich form, as shown in FIG. 5, the surface layer and the cured body are layered with [cured body-surface layer-cured body]. This may be arranged as [surface layer-cured body-surface layer]. By doing so, a unique viscoelastic function is generated, and it is possible to enhance the deformation function, sound insulation, waterproofness, and vibration absorption of the block.

Further, as described in claim 7, the adhesive portion 2
By using a heat generating material such as carbon fiber for electric power such as energization, microwave and high frequency for at least a part of them, selective heating can be performed. Therefore, when the adhesive portion 2 is a thermoplastic material, the cured body 3 can be heated and adhered or melted and peeled at an arbitrary time. As a result, the adhesive portion can be manufactured as an independent film, and the position of the surface layer piece and the hardened body that has been cast can be corrected, so that the block can be easily manufactured. In addition, when the block is replaced due to wear or the like, the removal and replacement work of the surface layer piece 1 can be easily performed by heating, so that there is an advantage that the cost of repair and treatment is significantly reduced.

Further, when the plate-shaped separator 33 having a discontinuous space is provided in the hardened body as described in claim 8, even if a load caused by a vibration or movement of the substrate after the start of operation is received, the block The fracture surface of is forced at the position of the separator 33, and a crack is generated only at this position. Therefore, it is possible to prevent chaotic fluctuations and breakage of the blocks and greatly improve the durability of the bond. The separator 33 exerts the function of collecting the generated cracks similarly in a space which is divided and a space in which the small plate pieces are buried.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION A general block according to the present invention mainly uses a tread portion of a tire, and one block is manufactured by combining one to an arbitrary number. The block is molded into a square having a side of 120 mm to form a surface layer piece 1, and a set of four pieces is used for one block. The surface layer pieces are arranged with an interval of 4 mm. First, asphalt is applied with the back side of the tread facing up, and concrete is placed on this. Rubber thickness 10 mm, asphalt thickness 1
In case of mm, concrete pouring thickness shall be 19 mm. Change the casting thickness according to the change of rubber thickness, 246x246x30mm
Mold into blocks. When the concrete hardens, the rubber surface layer pieces and hardened concrete are integrated to complete the block. Since 4 pieces are lined up in 1 m when the joint spacing is 4 mm, 16 pieces are arranged in a square area of 1 square meter. Arranging these on a base 6 of concrete or paving sand provides a multifunctional block pavement, and when used vertically, a rubber wall can be obtained. This method makes it possible to control the thickness of the block on which the rubber piece is pasted to the desired thickness regardless of the difference in the thickness of the surface layer piece. Join together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One of the embodiments of this block will be described below with reference to FIG. 1, which is a vertical sectional view of the embodiment when construction is completed. First, a square rubber piece taken out by cutting the tread portion of a rubber tire is used as a surface layer piece 1 and formed into a rectangular flat plate shape, and the rubber piece is arranged at a position to cover the surface of the block. The asphalt is applied to the back side of the surface layer piece 1 to form the adhesive portion 2. Concrete is directly placed on the adhesive portion 2. In this concrete, the entire block is cast into a predetermined shape. By the subsequent curing, the cured body 3 having a constant strength is formed, and the surface layer piece 1 and the cured body 3 are joined by the adhesive portion 2 to be integrated. Surface piece 1
The asphalt adhesive portion 2 was adhered to the concrete, and the concrete was poured and cured as the hardened body 3. After the adhesion, the rubber-clad block was completed. These blocks are the groundwork of the road surface 6
With the arrangement, the running noise of the vehicle is significantly reduced, and the ice on the surface can be easily removed by the passing vehicle to prevent a slip accident. It can also be used for walls for the purposes of sound insulation, waterproofing, shock absorption, and scour prevention.

As described in claim 1, since the adhesive portion 2 is asphalt, the surface layer piece 1 and the hardened body 3 at low temperature.
The partial peeling that has occurred during the period is repaired at high temperatures. In addition, since adhesion and peeling of the surface layer can be easily controlled by heating and pressing, construction and repair are facilitated.

As described in claim 2, a part of the hardened body 3 is extruded as a joint body 34 into a part of the joint space 4 between the rubber pieces. This has the function of transmitting the horizontal acting force received by the surface layer piece 1 to the hardened body 3 to resist it, and it is also possible to embed a formed article such as plastic or metal and substitute it.

[0021] As described in claim 4, the rubber holding arm 7 is baked and embedded in the hardened body 3.
The holding arm 7 has a function of preventing the surface layer piece 1 from peeling and moving and ensuring the safety of traffic. If the holding arm 7 is made thicker or a hole is made in the holding arm, the holding arm 7 is held by the undercut of the hardened body 3, so that the bonding strength is increased.

As described in claim 5, the independent blocks are connected by the mesh body 5 to improve the construction efficiency and to exert the function of preventing the peeling by transmitting the local horizontal force to the other blocks to disperse them. is doing.

FIG. 2 is a top view of the first embodiment described above. As described in claim 6, the transverse cutting line 11 and the edge line 12 are orthogonal to each other. A slight undulation on the back of the tire creates a complicated uneven shape on the adhesive surface, increases resistance to misalignment and prevents monotonous surface patterns, improving aesthetics.

FIG. 3 is a vertical sectional view for explaining a general manufacturing procedure. A square old tire processed rubber piece is arranged as the surface layer piece 1, and asphalt is poured to prepare the adhesive portion 2.
The net-like body 5 is buried in the middle, concrete is directly cast on the asphalt, and the hardening of the concrete and the adhesion by the asphalt are waited. On the right side of the two surface layer pieces 1, the transverse cutting line 11 is oblique. If the tire is radially divided into equal parts, this angle may be large. When the tread portion is cut out from the tire as a rectangle, the edge line 12 parallel to the traveling direction of the wheel is processed, and the cut surfaces of both lines facing each other at the time of arrangement of the surface layer are made substantially parallel to each other, so that the rubber is worn from around the joint 4. Greatly reduces the ride quality of the vehicle.

FIG. 4 is an upside down view of FIG. 3 and is a vertical cross-sectional view when it is used for fixing rubber to the surface such as a car stop or a seawall.

FIG. 5 is a vertical cross-sectional view of an embodiment in which the surface pattern side of the tread is adhered and processed into an antifreeze liquid spraying system. As described in claim 8, the rubber surface layer pieces are sandwiched between the upper and lower cured bodies. When the thickness of the surface layer piece and the number of layers are increased, the elastic displacement of rubber increases. If such blocks are arranged in the pond of the antifreezing liquid 22,
The surface of the block is lowered by the load of the passing vehicle and the antifreeze liquid 2
Apply 2 to the tire tread of the vehicle. Since this liquid is spread on the road surface, the spraying range of the liquid is expanded to prevent freezing. In the summer, the liquid can be replaced with water and used as a watering system.

[0027]

As described above, in the rubber-coated block of the present invention, a block having a desired design dimension can be manufactured by a simple and inexpensive method regardless of the thickness of the rubber layer, and the shape of the adhesive surface with the cured product can be obtained. Regardless of the type, it is joined with a tightly bonded adhesive surface to increase durability, secures the bonding strength to withstand heavy loads such as vehicle traffic, and the bonding surface becomes a flat surface with a complicated shape, greatly improving the shear strength of the adhesive surface However, when used for paving, the noise level and the reverberant sound are reduced, and it is possible to remove surface icing by a passing vehicle. Also, it is used in places where it is worn due to friction with falling material such as seawalls and ditches to improve durability. In addition, the use of fences, walls, stepping stones, and the like has the effect of reducing the reverberant sound and preventing injuries and damages caused by the collision of people and objects, thereby making the environment comfortable and safe. In addition, in the disposal of rubber materials after use, the generated heat and gas are reduced as compared with other methods, which is effective in preventing pollution of the global environment.
